The exothermic F + H(2)O → HF + OH reaction has a decidedly "early" or "reactant-like" barrier. According to a naïve interpretation of the Polanyi's rules, translational energy would be more effective than vibrational energy in promoting such reactions. However

Iron-bearing phyllosilicates strongly influence the redox state and mobility of uranium because of their limited hydraulic conductivity, high specific surface area, and redox reactivity. Standard extraction procedures cannot be accurately applied for the determination of clay-Fe(II/III) and U(IV/VI) in clay
